grid attribute not checked when doing compset matches

[billsacks]

config_compsets.xml files occasionally list a grid attribute on the compset line. An example from cime is:

  <compset grid="r%rx1">
    <alias>AIAF</alias>
    <lname>2000_DATM%IAF_SLND_DICE%IAF_DOCN%IAF_DROF%IAF_SGLC_SWAV</lname>
  </compset>

According to @mvertens (see discussion on #1582 ), this is supposed to stop you from creating a case with the given compset unless the grid matches the given expression. But this doesn't seem to be working. For example, cime master let me run the following without complaint:

./create_test --no-build --test-root . SMS.f19_g16_r01.AIAF.yellowstone_intel

• where I'm using a rof grid that does not match 'r%rx1'.

(For the record, I don't view this as "critical", but @mvertens asked me to add that label.)

I think that trying to use the grid attribute in this file creates a circular reference situation in which the compset is needed to get the grid but the grid is needed to get the compset.

The result of discussion - this is a circular dependency and the grid attribute should be removed from config_compsets.xml

@billsacks - I am assigning this to you since you had a clear idea of where compsets had a grid attribute.
